Definition
- Noun:
- A type of carbohydrate: A trisaccharide is a sugar molecule composed of three monosaccharide units linked together. It is hydrolyzed to yield exactly three monosaccharide molecules upon complete breakdown.
Usage Examples
- Noun:
- Raffinose is a common trisaccharide found in beans and some vegetables.
- The digestion of the trisaccharide required a specific enzyme to break its bonds.
Advanced Usage
- In Biochemistry: The term is used precisely to classify sugars based on the number of monosaccharide units. A trisaccharide is intermediate in complexity between disaccharides (two units) and polysaccharides (many units).
- The researcher studied the transport mechanism for the trisaccharide across the cell membrane.
Variants and Related Words
- Monosaccharide (n): The simplest form of sugar, a single unit (e.g., glucose, fructose).
- Disaccharide (n): A sugar composed of two monosaccharide units (e.g., sucrose, lactose).
- Oligosaccharide (n): A carbohydrate whose molecules are composed of a relatively small number (typically three to ten) of monosaccharide units. A trisaccharide is a specific type of oligosaccharide.
- Hydrolysis (n): The chemical process of breaking a bond in a molecule using water, which is how a trisaccharide is broken down into its components.
Synonyms
- Triose sugar: (Less common, more general) This term is ambiguous as "triose" typically refers to a monosaccharide with three carbon atoms, not a three-unit sugar. "Trisaccharide" is the precise and preferred term.
- Oligosaccharide: This is a broader category that includes trisaccharides.
Related Phrases
- "Yield upon hydrolysis": A common phrase describing the result of breaking down a carbohydrate.
- This trisaccharide yields galactose, glucose, and fructose upon complete hydrolysis.
